Emergency rooms operate under conditions that no other medical setting faces: critically ill patients arriving without warning, limited information about medical histories, time pressure that makes thorough evaluation difficult, and a constant flow of cases competing for attention. These conditions create fertile ground for errors—and when those errors cause harm, they create grounds for medical malpractice claims.
What Makes ER Malpractice Different
Emergency physicians don't have the luxury of scheduled appointments with established patients whose histories they know. They meet people in crisis, often unable to communicate clearly, and must make rapid decisions based on incomplete information. This context matters legally because the standard of care in emergency medicine accounts for these constraints.
That said, emergency conditions don't excuse negligence. The standard of care for emergency physicians isn't perfection—it's what a reasonably competent emergency physician would do under similar circumstances. Missing a subtle diagnosis that would only be apparent with extensive testing might not be negligent. Sending home a patient with classic heart attack symptoms without an EKG almost certainly is.
Common Types of ER Errors
Emergency room mistakes tend to cluster in predictable categories. Misdiagnosis and delayed diagnosis top the list—the patient whose heart attack gets called anxiety, whose appendicitis gets dismissed as gastritis, whose stroke symptoms get attributed to inner ear problems. These diagnostic failures often result from cognitive shortcuts, inadequate testing, or failure to consider dangerous possibilities in the differential diagnosis.
Delayed treatment causes harm even when diagnosis is correct. The patient correctly identified as having sepsis but not given antibiotics for hours. The stroke patient who waits too long for the CT scan that would enable treatment. The trauma victim whose internal bleeding isn't addressed quickly enough. Time matters in emergency medicine, and delays that wouldn't matter in other contexts can prove fatal in the ER.
Discharge errors send patients home when they should be admitted, or release them without adequate instructions or follow-up arrangements. The patient discharged with "viral syndrome" who actually has meningitis. The chest pain patient sent home with antacids who dies of a heart attack that night. These errors represent failures of the safety net that emergency departments are supposed to provide.
Who Can Be Held Liable
Emergency physicians bear primary responsibility for the care they provide. When their diagnostic reasoning, treatment decisions, or follow-up arrangements fall below professional standards, they can be held personally liable for resulting harm.
Hospitals face liability as well, though the theories differ. Many emergency physicians are independent contractors rather than hospital employees, which historically shielded hospitals from vicarious liability for their negligence. However, hospitals can still be liable for their own failures: inadequate staffing that leads to dangerous delays, broken equipment that prevents proper diagnosis, systemic problems with communication or follow-up, and negligent credentialing of incompetent physicians.
Some states have adopted "apparent agency" theories holding hospitals liable when patients reasonably believe emergency physicians are hospital employees. If you went to the hospital's emergency department, you probably assumed the doctors there worked for the hospital—and courts increasingly hold hospitals to that reasonable expectation.
Proving Your Case
ER malpractice claims require the same basic elements as other medical malpractice: a duty of care (established when the ER undertook to treat you), breach of the standard of care, causation connecting that breach to your injury, and damages. Expert testimony is typically essential—a qualified emergency physician must explain what the standard of care required and how the defendant's actions fell short.
Medical records are critical evidence. ER records document triage assessments, vital signs over time, physician evaluations, tests ordered and results received, treatments given, and discharge instructions. These contemporaneous records often reveal exactly where things went wrong—the abnormal vital signs that weren't addressed, the test that wasn't ordered, the warning signs that were documented but ignored.
Special Considerations
Emergency room cases sometimes involve shortened statutes of limitations or special procedural requirements depending on the state. Some jurisdictions require pre-suit expert review or certificates of merit before filing. Time limits for filing may be shorter for claims against government-operated hospitals. Understanding these procedural requirements matters—missing a deadline or failing to comply with pre-suit requirements can doom an otherwise valid claim.
Damage caps in some states limit recovery in medical malpractice cases, including ER claims. These caps typically affect non-economic damages like pain and suffering while leaving economic damages for medical expenses and lost income uncapped. How these limitations apply varies significantly by state.
What to Do If You Were Harmed
If you believe an emergency room error harmed you or a family member, obtaining complete copies of all ER records is an essential first step. These records should be requested promptly, before any possibility of alteration or loss. Consulting with an attorney experienced in medical malpractice can help you understand whether the care you received met appropriate standards and whether you have grounds to pursue a claim.
